The first one is a sponge.

 

The second one, if you're talking about the green one, those are green star polyps. If you're talking about the out-of-focus tan background coral, it's Xenia. Or are you talking about that little tiny bit of green macroaglae behind the GSP?

doesn't really look like halimeda though.

 

I think it's Codium

I agree with Chris, it looks like the smaller variety of halimeda.

is the sponge bad or good

[ReeferMan]

usually its a sign of a established tank

it's good for diversity. It just filter feeds, and if it's growing, it's thriving. Looks nice.

 

 

On the macroalgae - does it look hard, like a rock that got covered in algae, or does it look more like a balloon that happens to be green colored?

 

 

 

Not sure what "smaller variety" you're talking about, davelin - have a species or other common name for it?

Looks like a macro-algae to me; one that Bemmer had (I have a small piece of it in my refugium). Growth pattern is kind of like a monti-digi (branching); but it's a macro-algae. If it's soft - put it in the refugium!
